Salicylic acid is the most effective of the known keratolytic compounds, and is most beneficial in extremely thick or scaly psoriatic plaques. The typical morphology is a 1-cm or larger well-demarcated red plaque surmounted by white or silvery scales. (Fig.1) The lesions can occur anywhere, but the most commonly involved areas are the elbows, knees, scalp, sacrum, navel, intergluteal cleft, and genitalia.
